Belief in common descent is largely derived from the similarity among forms of life. For example:
Belief in common descent is largely derived from the similarity among forms of life. For example:
*All cells are bound by a membrane
*All [[cell]]s are bound by a [[membrane]]
*All cells store heritable information as DNA.
*All cells store heritable information as [[DNA]].
*All cells adhere to the same basic mechanism of gene expression.
*All cells adhere to the same basic mechanism of [[gene expression]].
*All cells utilize the same metabolic pathways.
*All cells utilize the same [[metabolic]] pathways.
*All cells have ribosomes to produce protein.
*All cells have [[ribosome]]s to produce [[protein]].
From these similarities, an evolutionist infers that all life is related through one original life form.
